Sam Dietz once again returns to track down another serial killer this time played by William Forsythe that taunts the police by sending them pieces of his latest victims.
My idea of a third installment is a film that should stray more from the first and second entries to give people something they haven't seen before in terms of the series, RELENTLESS 3 doesn't stray at all but it is by no means a weak entry, in fact it is actually a good sequel for a third film in a series, the role of serial killer is once again perfectly cast, putting William Forsythe and the word creepy in one sentence works great because the man shines the most when he plays a creepy character, Leo Rossi who again plays the role of Sam Dietz gives a great performance as he did in the first and the second, but one of the scene stealers is Robert Costanzo whose character and performance added a somewhat light hearted touch to a series that's been very much serious up to this point.
The storyline is basically a detective vs. serial killer type as in the first and second, but unlike the second film it concentrates less on the character story and more on the killer like in the first one, plus the highlight of the story is the ending, if you think you can predict it you're a genius because it one of the best endings I've seen in a while.
Overall, better than the first but not quite as good as the second but its worth a watch.
